No mate. The 600kms was melb - wagga - wangarrata. Melb - Wagga is around 400ish kms. With a break it is 4 and a half hours.

I agree. Thats why I posted it. The more positives about the Ford product the better. Good to see that someone else got the same. I was starting to question myself :

Fords are the most economical big six on the market hooked up to a regular box.

BMW's 3.0 are the only other engine that really makes simular power, but better fuel economy (something to do with the 5er being 1500kg?)

Drove a Fairlane Ghia around a while back, was impressed with both city and highway economy.

Seems like faster warm up of the box plays a big part.. lookat at BF 4 speed to BFII.. .2l/100, seemingly just from improve auto efficency mostly from quick warmups.

Wonder how much of its calibration given the improvements that can be reaped with an edit on BA's?

you actually waste fuel by filling past the first click, according to one of my owners manuals, as the fuel evaporates and spills - it's hard to measure exact fuel useage - i tested the trip computer in my old Berlina, it was pretty spot on from what i could tell, the amount of litres it said it had consumed since it was filled, was replaced by the same amount on the next fill, and the distance travelled - well you can't even measure that one exactly yourself, as according to ADRs the vehicles odometer and speedometer is allowed to be +or-10% inaccurate. But according to the speed test on the Geelong Rd, my speedo was pretty accurate. Now the trip computer uses very simple mathematics calculating averages from the distance travelled and fuel consumed. But nobody could say they do it accurately as you could not get your measurements of fuel used accurate enough, and distance travelled as your odometer is not guaranteed to be accurate. And at the end of the day, what difference did your calculating make? to compare your fuel consumption with other cars, you have to go back and do the exact same driving in the exact same conditions to see which is better - thats why Window stickers are ok for me, telling me which car uses less and more in the same testing conditions.

I think most of the standard BF improvement came from (in my own personal order):
-Dual knock sensors
-Compression increase
-Dual VCT

With BFII
-Trans cooler/heater like ZF6 setup (or so I've gathered)

Aero talk is just that sexy press release talk. If its improving economy, its not showing on the 6 speed at all.

The cars with six speeds obviously are enhanced with extra ratios..

For a BA. I would say BFII auto box (or its transcooler/heater) would be a good bet. Reduce fuel consumption 0.2L per 100. Dual VCT should allow some more improvement 0.1-0.2L per 100..

Then I would imagine compression increases and adding 2nd knock sensors are more expensive and provide the most gain.

I don't think theres much that can be done to improve highway on BF/BFII with 6 speed other than Direct injection and further compression (and lose weight). Lightweight/low friction engine parts and a slightly higher compression ratio might also get you some very marginal gains.

Advanced Aero might get you another ~0.2L per 100km @ 100kmph.

City cycle has gains. Lose weight, restrict power, leaner ecu. BA ECU would seem to be not that economically tuned. You could improve whole litres.

Look at Audi, Merc, Lexus, Nissan. None have vechicals with much better economy in that class (other than diesels).
